Sorry to hear that mate, but unfortunately these scenarios happend way too often, and it due to the decision making process of the individual. He/She would have panicked and then just drive off, but i bet he/she will regret it once the cops get a hold of he/she. They freak out, dont know what to do and then just drive off in a cowardly manner. Hit and run accidents are pretty severe and cops take these offences very seriously. Consider your self lucky that nobody was hurt, a bouncing tyre at 100kph+ is a lethal weapon, all sorts of things can go wrong. At least you got out of it unscaved, dont worry about cash, cash can't replace your health. Keep us posted on how things eventuate, we dont have enough information on cases like this, it's all mods and things that get over covered and repeated. Would be good for novices to read up on previous experiences and be prepared on how to deal with such scenarios in case they happend. Cheers
